| 177 | Drilling tool for very small diameter openings and container therefor | US194436 | 1988-05-13 | US4922603A | 1990-05-08 | Wojciech B. Kosmowski |
| A high speed drilling system is disclosed for high spped drilling of very small holes in workpieces such as printed circuit boards. The A-Y positioning system includes air bearings to provide lift between the stationary guide beams, the crossbeam and the top table, and further includes a vacuum preloading apparatus for providing a preloading force between the table and the guide beam. The preload force dampens Z axis oscillations which can result in drill bit breakage. The top table is a lightweight honeycomb structure, whose effective rigidity is virtually that of the guide beam due to the vacuum preloading. The system includes pairs of spindles, one a conventional spindle for drilling holes large than about 0.125 inches, and the other a high speed spindle for drilling holes in the range of about 0.003 to 0.125 inches. The high speed spindle includes a stationary spindle body carry the stator of the rotary drive motor. Only the spindle rotor is translated along the Z axis to perform the drilling movements. The rotor is supported within the spindle body by rotary and linear air bearings, and is axially driven by a linear motor. A toolchanger loaded by clips carrying the frilling bits is mounted on the top work table, and minimizes the time required to change drilling tools. The clips minimize the manual handling of the fragile drill bits. A vacuum hold-down apparatus is employed to secure the workpieces to a drilling station. | ||||||
| 178 | Hollow granite box beam and method of forming | US383203 | 1989-07-21 | US4920723A | 1990-05-01 | Douglas R. Porter |
| A box beam comprises at least two elongated component blocks of granite, each containing at least one flat surface, the flat surfaces having identical dimensions. Igneous rock material is removed from the flat surface of at least one of the component blocks so as to form at least one open cavity in that component block. The interior cavity has boundary walls of a predetermined, though not necessarily uniform, thickness. The two component blocks are then bonded together along the remaining unremoved portions of the flat surfaces so as to form a box beam.The system described above for manufacturing hollow granite box beams reduces weight while maintaining stiffness comparable to that of the composite ceramic or metal beams along with the inherent stability of granite, e.g., low coefficient of thermal expansion, in a highly efficient manufacturing process. | ||||||

| 180 | Dowel hole drilling machine | US706497 | 1985-02-28 | US4639171A | 1987-01-27 | Johann Maier |
| The dowel hole drilling machine comprises a workpiece support. One part of the workpiece support and a crosspiece carrying the drilling unit are mounted to be pivotally movable in unison about an axis. That workpiece support comprises eccentrically mounted supports, which are adapted to be aligned and flush with the workpiece support and to protrude beyond a workpiece support, which extends at right angles to the workpiece support and is spaced the same distance from the pivotal axis as the workpiece support. The workpiece support serves to support the workpiece during a horizontal drilling operation. When the drilling unit is in a vertical position, the stops are flush with the workpiece support and serve as stops for the drilling of the first row of dowel holes. This results in an exact coordination of the drill and the workpiece support, which constitutes a stop for and defines the location of the reference edge during the horizontal and vertical drilling operations. That coordination will not be changed by the pivotal movement of the drilling unit. | ||||||
